Here is my webpage with a puzzle game I am making:
http://www.acsu.buffalo.edu/~jamesber/GameOne.html#
If you take a look at it, keep refreshing the page, it takes a second or two for all the components to load.
I thought it was that the ajax was loading slow but I don't think that is it. Someone please help! Thanks!

Use Firebug, you can see in the network tab which part is slow.
You should extract your javascript and css in seperate files, they can be compressed then.
As other users suggested - if you are loading 3rd party content from the internet, you have to keep in mind that download times may vary on each page refresh.
Anyway, my advice is to move your custom js code into separate file and minify it when you finish the development process.
And the most important: place that file just before </body> tag.
The reason for doing so is that scripts at the head of a page are blocking the browser. It must stop processing the website until all of the scripts are downloaded and parsed.
A great discussion about that matter is available on stackoverflow, you should go through it here.
A get-request for http://botanicalapp.com/api/v1/plants/?photo=true is taking around 2-3.5 seconds so you're probably not going to be able to process it faster than that.
I would advice you to move the script tag containing your sites javascript to the bottom of the page. It doesn't have to reside in head and putting it right before the closing tag of body allows other external component on the page to download as quickly as possible before the scripts are loaded.
Nothing seems to make it better. I was wondering. Is there a way to put like a smoother looking loading screen to cover it up? Was looking into a js spinner but couldn't get that to work right. But could this be done?

Okay, basically what I want to try to achieve, is when a dragover event fires from HTML5 Drag And Drop API, I wish to create a jQuery draggable object, and start following the mouse around, while the dragend event fires from the HTML5 Drag And Drop API.
The reason I want to do this, is the following:
I have an application which uses a plugin, that has a functionality, which is dependent on the jQuery.ui draggable to function (it is the FullCalendar Scheduler plugin, version 3)
I want to achieve a new functionality in the application, with which the client can drag something from browser window A, and drop it in the above mentioned plugin in browser window B.
As the above mentioned plugin is not working with the native HTML5 Drag and Drop API, and the jQuery.ui draggable is not capable of dragging elements from one browser window to the other, I think my only option is to mix these two plugins.
My proposed solution to this problem was, using the native HTML5 Drag and Drop API, and when the dragged element reaches over a dropzone, creating a new draggable element in browser window B, and simulating a mousedown event on it, so it starts following the cursor. When the dragend event would fire, I planned to plain and simply fire the mouseup event on the draggable element also, and from here on the scheduler plugin can do it's magic.
To try to test this out, with a single browser window at first, I've tried to achieve the first part of my above solution, ie: when the dragover fires, create the jQuery.ui draggable and simulate a mousedown on it, then it should start following the mouse. I can't achieve this behaviour.
I made a fiddle, where you can see what I tried so far (I am not posting the whole code here, as it is rather long): JSFiddle
Basically, the error I am getting at the Fiddle, with both options that I tried, is a type.indexOf is not a function error.
I also asked and received some help on the following question, from where the proposed solution works fine when starting the drag operation with a click event, but it isn't working with any other event type. I pressume, I can simulate a mousedown.draggable event, only from a MouseEvent, and the dragend event is not a MouseEvent.
Long story short, I would need help in obtaining the result I am looking for, at least for the first part of my proposed solution!
There does not appear to be a good answer for this. First, not all browsers support the same DnD terminology or functionality. Such as FireFox fires a dragenter event on drop and Chrome does not seem to detect a drop event when the object is from another window.
Here is my testing so far. To use, copy the content into a Text file and save as HTM or HTML. Then Open the file locally in your browser. Open another Window and open the second HTM. now you have two windows you can drag to and from.

As you can see, this is using raw JavaScript. I was tinkering with jQuery UI, and I kept the stylesheet just for easy theming. We have a section to print out log details, a draggable, and a static item.

Window B uses jQuery as the intention was to convert the element into a jQuery UI Draggable.
First thing to know, there is no way to do in transit. Since the Source element is not a part of the target DOM, it cannot be done. It can be added and initialized as a Draggable in the drop event. Essentially what will happen is a new element will be created at that time assigned all the data.
Second, data transfer is unreliable and I would avoid DataTransfer as your data container. I would advise using localStorage. This is similar to a cookie and is a lot more reliable.
For example, I created the following Data object:
{
id,
type,
attr: {
id,
class,
width,
height
},
content
}
Here are some example functions:
function collectData(obj){
return {
id: obj.attr("id"),
type: obj.prop("nodeName"),
attr: {
id: obj.attr("id"),
class: obj.attr("class"),
width: obj.width(),
height: obj.height()
},
content: obj.text().trim()
};
}
function saveData(k, d){
localStorage.setItem(k, JSON.stringify(d));
}
function getData(k){
return JSON.parse(localStorage.getItem(k));
}
function makeEl(d, pObj){
return $("<" + d.type +">", d.attr).html("<p>" + d.content + "</p>").appendTo(pObj);
}
$("#draggable").on('dragstart', function(e){
saveData("drag-data", collectData($(this)));
});
$("#dropzone").on('drop', function(e){
var item = makeEl(getData('drag-data'), $(this));
item.addClass("clone").position({
my: "center",
of: e
}).draggable();
});
In theory, this should all work. In practice, I have hit a ton of roadblocks. I would suggest something like a click-to-copy type of action. Where the User clicks an item in Window A (selecting it) and then clicks where they want it to be in Window B. Again using localStorage, the item could be cloned into the new location.

I know this is not the answer you're looking for, and for that you need to try to ask the real question. You seem to keep asking around the question.
Hope this helps.
I am having trouble with my html page here. On the console it shows me that there is 1 error on line 92 due to an unexpected token. Im trying to drag the image on the page to a designated box. Once dragged it should stay in the box. When I click on the image i should be able to drag it out of the box. I am not sure where i went wrong, but its completely not working at this point. All help is appreciated.

I think you just got a little overzealous with some editing... A few typo's and I think you're good:
Missing the $ on the line " (".leftImg").draggable({"
The line var randomNumber = Math.floor(Math.random() * pictureIds.length) needs to have pictureIds.length changed to pictureIds as it is an int not an array.
Your loop is on the variable i but you incremented pictureId's instead of i.
The part where you are doing table.row.add had Res[image id] and I am not sure what is supposed to be in place if image id but Res[image id] is not valid. I commented that out in the code below but what I have edited below is draggable into the box.
$(document).ready(function() {
var pictureIds = 20;
var Size = 400;
var table = $('#results').DataTable();
$.get("https://unsplash.it/list", function(Res) {
for (var i = 0; i < pictureIds; i++) {
var randomNumber = Math.floor(Math.random() * pictureIds);
$('.left').append($("<img>", {
src: "https://picsum.photos/" + Size + "/" + Size + "?image" + Res[randomNumber].id,
id: randomNumber,
class: "leftImg"
}));
}
$(".leftImg").draggable({
revert: "invalid"
});
$("#right").droppable({
accept: ".leftImg",
drop: function(event, ui) {
ui.draggable.attr("id"),
$(ui.draggable).detach().css({
top: 2,
left: 0
}).appendTo($(this));
window.alert("Dropped image with an ID of " + ui.draggable.attr('id'));
//Create rows

I am a student and I am trying to start, pause and start a gif when a user clicks the gif, however I am stuck on how to add in this click function. I know that the the gif version of the object is .images.fixed_height.url and the still image is .images.fixed_height_still.url . If I try to append like below $(this) I get that images is undefined. How would I go by doing this? Currently 10 gifs show when you click the category. Thank you for any help in advance.

The difference between fixed_height and fixed_height_still will solve the problem. if you look closely the urls differ only by name_s.gif and name.gif.
So you can simply swap the two images to create a player. This will act like a play and stop. Not play and pause. But in a small gif I don't think pause really matter, stop and pause will look similar.
adding class name to the #photo
$("#photo").append('<img class="gif" src="' + response.data[i].images.fixed_height_still.url + '">');
event handler which will control play and stop
$('body').on('click', '.gif', function() {
var src = $(this).attr("src");
if($(this).hasClass('playing')){
//stop
$(this).attr('src', src.replace(/\.gif/i, "_s.gif"))
$(this).removeClass('playing');
} else {
//play
$(this).addClass('playing');
$(this).attr('src', src.replace(/\_s.gif/i, ".gif"))
}
});
jsfiddle demo
https://jsfiddle.net/karthick6891/L9t0t1r2/
you can use this jquery plugin http://rubentd.com/gifplayer/
<img class="gifplayer" src="media/banana.png" />
<script>
$('.gifplayer').gifplayer();
</script>
you can control like this
Use these methods to play and stop the player programatically
$('#banana').gifplayer('play');
$('#banana').gifplayer('stop');

I need to make an infinite wall which will pull text from database and show it on the wall. I have written this code -
$(function() {
var x = 0;
var y = 100.0;
var z=0;
setInterval(function() {
x -= 0.1;
y -= 0.1;
z++;
if (x <= -100.0){
$("#h1d1").html("loop div 1 :" + z);
x = 0;
}
if (y <= 0){
$("#h1d2").html("loop div 2 :" + z);
y = 100.0;
}
$('#movimg1').css('left', x + "%");
$('#movimg2').css('left', y + "%");
}, 10);
$("#stopbutton").click(function() {
$('#movimg1').stop();
});
})
But the text are not behaving as I wanted it to behave. It changes in the middle of the screen which I don't want. I need the text to change when it is out of view.

A couple more things- I want to add a play/pause button. Any advice on how I could achieve that would be much appreciated. Also I want the divs to be inside #wrap div, but if I change the position attribute to relative, the divs don't remain together.
Thanks in advance.
The problem was in the conditions.
if (x <= -100.0) {
z++;
$("#h1d1").html("loop div 1 :" + z);
x = 100; /* change this line */
}
if (y <= -100.0) { /* change this line */
w++;
$("#h1d2").html("loop div 2 :" + w);
y = 100;
}
the conditions says that if any of these two divs reaches left:-100% then the element must place at the end of queue at left:100%.
And one other thing you can combine these if statements and only use x to do the transition.
For start and stop button to work, you should kill the simulation to stop by using clearInterval() function, and call doSimulate() to start again:
var started = true;
$("#stopbutton").click(function () {
if(started) {
clearInterval(sim);
$(this).html('Start');
started = false;
}else{
doSimulate();
$(this).html('Stop');
started = true;
}
});
Here is jsFiddle With Start/Stop Working.
Look at this JSFiddle, i added one more to get a smooth transition back to start.. The third should contain same message as first.
HTML
<body>
<div class="row">
<div class="col-xs-1"></div>
<div id="wrap" class="col-xs-10">

}
$('#movimg1').css('left', (x-200) + "%");
$('#movimg2').css('left', (x-100) + "%");
$('#movimg3').css('left', x + "%");
}, 10);
}
start();
$("#stopbutton").click(function () {
window.clearInterval(interval);
$(this).hide();
$("#startbutton").show();
});
$("#startbutton").click(function () {
start();
$(this).hide();
$("#stopbutton").show();
});
})
CSS
body {
overflow: hidden;

Now with Stop and Start buttons: JSFiddle
I want to change image every 10 seconds in javascript, can someone help me?
Here's the images, I only want add some code on javascript without changing these code below
HTML
<body onload = "imageChanger()">
<div>
<ul>
<li><img src = "images/img1.jpg"/></li>
<li><img src = "images/img2.jpg"/></li>
<li><img src = "images/img3.jpg"/></li>
<li><img src = "images/img4.jpg"/></li>
</ul>
</div>
</body>
CSS
div {margin: 50px auto; height: 500px; width: 800px; overflow: hidden; border: 10px solid;}
img {width: 800px; height: 500px;}
ul {list-style-type: none; padding: 0; margin: 0;}
I want to add some code that will change image on load:
JS
function imageChanger()
{
//Code here
}
Here is what I did for a similar scenario.
<body id="background">
<script>
$(function () {
var imageArray = ['BG-1.jpg', 'BG-2.jpg', 'BG-3.jpg', 'BG-4.jpg', 'BG-5.jpg', 'BG-6.jpg', 'BG-7.jpg', 'BG-8.jpg', 'BG-9.jpg', 'BG-10.jpg', 'BG-11.jpg', 'BG-12.jpg', 'BG-13.jpg', 'BG-14.jpg', 'BG-15.jpg', 'BG-16.jpg', 'BG-17.jpg', 'BG-18.jpg', 'BG-19.jpg', 'BG-20.jpg', 'BG-21.jpg', 'BG-22.jpg']
// on page load
$('#background').css({ 'background-image': 'url(/Content/img/BackGround/' + imageArray[Math.floor(Math.random() * imageArray.length)] + ')', 'background-size': 'cover' })
// every 10 seconds change to random image name in the array
setInterval(function () {
$('#background').css({ 'background-image': 'url(/Content/img/BackGround/' + imageArray[Math.floor(Math.random() * imageArray.length)] + ')', 'background-size': 'cover' })
}, 10000);
});
</script>
</body>
You can use setInterval() for this.
Code
var i = 0;
setInterval(changeImage, 10000);
changeImage(); //Initial call to hide the images on start
function changeImage() {
i = (i + 1) % $('li').length; //Make sure the list wraps back to 0
$('li:eq(' + i + ')').show().siblings().hide();
}
